Which 1980s McDonald’s product used the short-lived brand name McDLT?

The McDLT hamburger used the short-lived McDLT brand name.

McDonald’s introduced the McDLT in the 1980s as a hamburger served in packaging that separated the hot side from the cool side. The meat and bottom bun were kept apart from the lettuce, tomato, and other cold ingredients until the customer assembled the sandwich.

The product’s name was a stylized abbreviation of McDonald’s and BLT, referencing the bacon, lettuce, and tomato association. Its packaging was central to the product’s identity and advertising, not merely a delivery detail.

The McDLT was discontinued in the early 1990s, partly because the polystyrene packaging used for it became controversial. It is often confused with the later McLean Deluxe or with the Big Mac, but those were separate products with different branding and recipes.
